Place the following CA Top Secret files on a shared DASD volume:
Security file
Audit/tracking file
Recovery file
If sharing a security file between multiple CPUs, specify the control option SHRFILE(YES) on each CPU.
Back up the security file from one CPU only. Omit the BACKUP DD statement or code the BACKUP(OFF) control option on all systems but one.
If “secured” data sets reside on shared DASD volumes and CA Top Secret is being used through one CPU only (usually during transition), system 913 abends may occur. Use program TSSPROT to remove the protection bits from the affected data sets. TSS Control Option ADSP should be set as ADSP(NO) to prevent future data sets from being marked as protected.
